Which language is the official language of the Republic of the Congo?

The official language of the Republic of the Congo, which has its capital at Brazzaville, is French.1

While French serves as the official language and the medium for educational instruction, the country is home to a diverse linguistic landscape. Most indigenous populations speak Bantu languages, with the exception of certain groups in the northeast. Additionally, two trade languages are widely used for intergroup communication: Lingala, which is common north of the capital, and Kituba, which is prevalent in the region between Brazzaville and the coast.1
